Item Name Descriptions
1 AC : AC power input indicator: the LED lights when the AC inlet has
100~240VAC input.
2 SOL :
Solar power input indicator: the LED lights when SOL terminal is
connecting to a solar panel and the solar panel input voltage is
over 12V.
3 CHA : Charging indicator: the LED lights when BAT terminal is
connected to battery and charging
4 LOA :
Loading indicator: the LED lights when the rear panel output
terminal is connecting to a device and offering power.
The LED always on when power ready.
5 REV : Battery polarity reverse indicator: the LED lights when the battery
polarities are reversed.
6 DATA IN Data Input Jack: the lower RJ45 jack, used for data input.
7 PoE OUT PoE Output Jack: the upper RJ45 jack, used for PoE output,
8 SOL : Solar Panel Terminal: used to connect the solar panel.
9 BAT :
Battery terminal: used to connect the battery.
NOTE: ALWAYS CONNECT THIS TERMINAL FIRST AND
DISCONNECT LAST.

O eration Guide
1. Connect the battery to the BAT terminal. Make sure the polarities are
correctly connected. Sequentially connect the solar panel to SOL terminal
and connect AC source to AC inlet. (If solar panel or AC source is
installed before the battery, and if the polarities of the battery be reversed,
then the battery will be disconnected.
2. Make sure the battery is properly connected to the unit. If no battery is
connected, then no voltage at BAT terminal.
3. When a solar panel and AC input are connected to the charger, if the
voltage of solar panel is higher than 15V, then solar panel is always the
main power source of the charger.
4. If only solar panel be used as the power source, then if solar panel
voltage lower than 10.5V, will stop charging. The solar panel cannot be
used stand alone without battery connected.
5. If only AC be used as the power source, then the load outputs will be
powered even without battery connected.
10 LOAD : Load Terminal: wire size up to 12AWG, the output voltage is the
same as battery voltage.
11 AC AC inlet: for 100~240VAC input.

User’s Manual SOL20A12LFP-56D2N
6. When charge from solar panel, as the battery full and turn to floating
stage, the CHA light will start flash.
7. When charge from AC, as the battery full, the CHA light will be turn off.
8. When battery connect to BAT terminal and with valid voltage, then the
LOA indicator will always light on even no load connected.
9. It can be two separate outputs on the rear panel, make sure the total
draw is not over the limit 20A.
10. The solar input, and battery(- are not the same grounding, must be
properly isolated.
11. When all power sources failed, the loads will be powered from battery
immediately with no interrupted, until the battery voltage lower than 11V
+/- 0.3V.
12. When any power source recover, the battery will be charged if the
battery voltage more than 6V. when the battery voltage back to 12V, the
load will be powered again.

4.0 Protection:
4.1 Battery Polarity Reverse Protection:
If only battery connected to terminal, when the battery polarities were reversed,
the model will stop output and REV indicator light on.
When the battery be removed and re-connected to terminal, the function will be
disable, if there is AC power sources connected, when the battery polarities
reversed, the battery will be disconnected, the load will be powered from AC
directly.
4.2 Battery Over Discharge Protection:
Cuts off the load when the battery voltage is lower than 11V + 0.3V, and auto
recover when the battery voltage returns to 12 V + 0.3V
4.3 Battery Over Charge Protection:
Fuse control, over 25A, the fuse will be burnt.
4.4 Solar Panel Polarity Reverse Protection:
When solar panel polarities be reversed, the charger stop output, it won’t damage
the charger or end device

User’s Manual SOL20A12LFP-56D2N
4.5 Solar Panel Over Charge Protection:
When charge current over 25A, the fuse will be burnt.
4.6 Output Short Circuit Protection:
When the rear output terminal or PoE output be short circuit, protection be active,
the product stop output and auto-recover when the terminal back to normal
connection.
4.7 Battery Output Current Limit:
The fuse will be burnt when battery output current over 25A
4.8 Load Output Voltage Limit:
The output voltage on the rear terminal normally is the same as battery.
